OBJECTIVE: Authors tested the hypothesis that one night of total sleep deprivation (TSD) would accelerate antidepressant response to paroxetine, as compared with TSD+placebo (PBO) and paroxetine-alone, in late-life major depression. METHODS:Eighty elderly outpatients with current episodes of non-psychotic, non-bipolar major depression were randomly assigned to one of three treatment conditions: TSD+paroxetine (N = 27), TSD + PBO (N = 27), and paroxetine-only (N = 26). Primary outcome was percentage of subjects in each condition who demonstrated early response (Hamilton Rating Scale for Depression scores [Ham-D: 17-item] of < or = 10) or remission (score of < or = 7) on Day 14. RESULTS:Response rates after 14 days were 22% in subjects randomly assigned to the TSD + paroxetine condition, 41% in TSD + PBO, and 46% in paroxetine alone. Remission rates after 14 days were 11% in TSD+paroxetine, 22% in TSD + PBO, and 38% in paroxetine. After adjusting for baseline depression severity, there were no statistically significant differences in response or remission rates. CONCLUSION: Contrary to the study hypothesis, one night of total sleep deprivation did not accelerate onset of antidepressant response to paroxetine pharmacotherapy of late-life depression. The data suggest, rather, that the two interventions might have counteracted each other.
